It aims at the enhancement of antiseismic administration in city reconstruction at present. Some decision methods (Method of equal intensity, method of equal probability of exceedance, method of equal occurrence ratio) for fortification intensity in succeeding use period of existing construction were provided to meet higher levels of seismic fortification criterion and changing use of buildings. With earthquake risk analysis, it is useful for discussion on antiseismic endurance of construction.展开更多

文摘In this paper, according to difference of the characteristics of the existing structure from design structure, the authors defined fortification intensity of the existing construction during succeeding use. It aims at the enhancement of antiseismic administration in city reconstruction at present. Some decision methods (Method of equal intensity, method of equal probability of exceedance, method of equal occurrence ratio) for fortification intensity in succeeding use period of existing construction were provided to meet higher levels of seismic fortification criterion and changing use of buildings. With earthquake risk analysis, it is useful for discussion on antiseismic endurance of construction.
